Born in Budapest, he began his musical studies at the age of five and continued them at the Béla Bartók Conservatory in 1963, studying piano and composition. In 1968 he was admitted to the Franz Liszt Academy of Music, where he was a pupil of Pál Kadosa, Ferenc Rados and György Kurtág, graduating in 1973.
He won the Hungarian Radio Beethoven Competition in 1970, and made his first concert tour of the United States in the following year. He received the Liszt Prize in 1973, and the Kossuth Prize in 1978.

He won another in 2013 in the chamber category with Bartók works. American critic Harold C. Schonberg praised Kocsis' technique and piano tone.
